Building "Logical" Circuits

We will construct circuits with three switches, connected in the following ways:

• Build a pure series circuit, where switch A AND switch B AND switch C all must be closed for the bulb to light;
• Build a pure parallel circuit, where switch A OR switch B OR switch C could be closed for the bulb to light;
• Build a mixed circuit, where closing switch A OR (switch B AND switch C) would light the bulb;
• Build a mixed circuit, where closing (switch A OR switch B) AND switch C would light the bulb.
